You invite a girl who's helped you in the past you found on the street and let her stay without expecting anything, and the first thing she does is strip and offer you 'service' as thanks?
She certainly knows her Hentai situations!
I do agree with him on the bit where he questions why her husband would cheat on her...I don't know either.
That ending though...Why did you give her permission to go back?
I want a sequel where he takes her away from her cheating husband, or something, that'd be nice.
